DAVID GESSNER, OF WORCESTER, MASSACHUSETTS.

CLOTH-TREATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 666,382, dated January 22, 1901. Application filed October 4, 1898. Serial No. 692,636. (No model.)

To all whom, it may concern.-

Be it known that 1, DAVID GESSNER, a citizen of the United States, and a resident of \Vorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Cloth- Treating Machinery, of which the following is a specification.

My invention relates to a brushingma chine.

In the accompanying drawings, Figure 1 is an isometric view of the front and one end. Figs. 2 and 3 are details. Fig. 4 is an isometric view of the front and other end of the machine with the brushing-cylinder cut away for clearness of illustration. Fig. 5 is a detail of the folder-gearing. Fig. 6 is a section at right angles to the brush-shaft through the middle of the machine. Figs. 7 and 8 are details.

The frame consists of the end members 1 and 2, with suitable cross-ties, also of the folder-carrying stands 3 and 4, also the brackets 5 and 6. The broken line 7 shows the course of the cloth through the machine as it is passed from a scray 8 successively to the brush 9, acting on the back of the cloth, draftroll 10, the steamer 11, main brush 12, acting on the face of the cloth, rear draft-roll 13, folder draft-roll 14, and folder 15.

The mechanism for supporting the main brush 12 and presenting the cloth thereto may be described as follows:

On the top of the end frames 1 and 2 are the stands 16 and 17, containing the bearings of the brush-shaft 18, which shaft is held on its bearings by the removable caps 19 and 20.

21 and 22 represent a loose and fast pulley for the belt by which the shaft 18 is driven.

23, 24, 25, and 26 represent a compound pulley formed of one casting, fixed on the shaft 18. The part 23 constitutes the pulley for driving the brush 9, and parts 24, 25, and 26, of three different diameters, constitute a step-pulley for driving the feed. The compound pulley 23, 24, 25, and 26 is provided with a hub adapted to be fixed on either end of the shaft 18, and pulleys 21 and 22 are provided with a sleeve 29 and collar 29, so that the brush may be reversed end for end by slipping these pulleys off the ends of the shaft 18, removing the caps 19 and 20, turning the brush end for end, and replacing the caps and placing the pulleys on opposite ends of the shaft.

The hand-wheel 30 is connected through the shaft 31 and bevelgears 32 and 33 with the shaft 34. The shaft 34 is connected by the spiral gears 35 and 36 with the screw-shaft 37 and by corresponding spiral gears (not shown) with the screw-shaft 38. The screwshaft 37 is fixed against longitudinal movement in bearings 39 40 and is held by said bearings parallel with the guideway 41, running horizontally on the side of the end frame 1, near its top. The screw-shaft 38 is fixed against longitudinal movement in similar bearings and held by said bearings parallel with the guideway 42, running horizontally on the inner side of the end frame 2, near its top.

43, 44, 45, and 46 are the guide-rolls, by the relative movement of which the cloth is pressed against or removed from the brush 12. By locating these guide-rolls in the position shown and providing for the lateral movement of at least three, and preferably all four, of them I am enabled 'to conduct the cloth tangentially against the same brush at three points of its circumference, Whereas I believe that heretofore it has never been presented to the brush atmore than two points. The axes of the guide-rolls 43 and 46, around which the cloth passes to and from the brush, are located in the same or nearly the same horizontal plane below the level of the brushshaft 18. The rolls 44 and 45 are located above the level of the brush-shaft 18, so that the cloth passes over the top of the brush.

The means by which the lateral movement of the guide-rolls 43, 44, 45, and 46 is produced at one end from the shaft 37 is the same as that by which it is produced at the opposite end from the shaft 38, and a description of one will suffice for both.

47 and 48 are inversely inclined screwthreads. 49 and 50 are other inversely-inclined screw-threads. The screw-thread-48 is also inversely inclined with respect to the screw-thread 50 and the screw-thread 47 with respect to the screw-thread 49. The screwthreads 49 and 50 are of like diameter and are of smaller diameter than the screw-threads 47 and 48, which latter are like each other in diameter.

51, 52, 53, and 54 are carriages mounted to slide in the guideway 41. They are threaded, respectively, onto the screw-threads 4'7, 48, 49, and 50. The carriages 51 and 52, respectively, carry the bearings of the guide-rolls 43 and 46. The carriage 53 is pivotally connected with one arm of the angle-lever 55 56, which has a fixed fulcrum at 57 and carries the roll 45 at the extremity of its other arm. The carriage 54 is pivotally connected with one arm of the angle-lever 58 59, having a fixed fulcrum at and carrying the guideroll 44 at the extremity of its other arm. hen the the screw-shaft 37 is rotated in one direction, the guide-rolls 43, 44, 45, and 46 will all approach the brush l2, and by the proper inclination of the screw-threads their relative movements are so timed that what ever slack in the cloth is produced by'the movement of the rolls 44 and 45 is taken up by the movement of the rolls 43 and 46. Conversely, when the shaft 37 is rotated in the opposite direction it causes the guide-rolls to retreat from the brush 12 with such relative movement that the slack produced by the retreat of the rolls 43 and 46 is taken up by the retreat of the rolls 44 an d 45. The approach of the four guide-rolls toward the brush presses the cloth against it at three points of its circumference, as shown in Fig. 6, while their retreat removes the cloth from the brush to any distance required. All of this is accomplished by the operator by simply turning the hand-wheel 30, without necessitating the stopping of either the running of the brush or the travel of the cloth through the machine.

By simply removing the cloth from the machine and moving the levers 58 59 and 55 56 so as to separate the rolls 44 and 45, to a distance as great as the diameter of the brush and removing the bearing-caps 19 and 20 the brush may, without disturbing the position or adjustment of any other part, be raised bodily and repaired, reversed, or replaced. The shafts 34, 37, and 38 being all located beneath the level of the brush-shaft 18 provents either of them from intercepting the necessary path of removal upward of the shaft 18. The rolls 44 and 45 are provided with open bearings, as shown in the lever-arms 59 and 56, so as'to permit of their being lifted out of their bearings, if desired. Since the levers 55 56 and 58 59 diverge from their upper extremities downward, they will carry the guides 44 and 45 in arcs indicated by the dotted lines a and b, to which the brush-radii c and d (at about forty-five degrees to the horizontal) are tangent. Therefore the movement of the guides 44 and 45 will be such as to cause the cloth to approach or recede from the brush at the three points 6, f, and 9. Since the guides 44 and 45 move substantially at forty-five degrees to the horizontal and the guides 43 and 46 move in a horizontal plane, it is necessary that the guides 43 and 46 should move farther than the guides 44 and 45, so that the resultant of the horizontal movement of 43 and 46 shall on a line at forty-five degrees to the horizontal substantially equal the movement of 44 and 45. This result is accomplished by the proper inclination of the screw-threads 47 and 48 with respect to the screw-threads 49 and 50 and the lever-arms 55 56 and 58 59. Although the unison ofmovement between the guides 43 44 and 45 46-that is to say,their simultaneous movement either toward or from the brushto a predetermined distance is accomplished by having the actuating screw-th reads mounted on the same shaft 37, nevertheless I do not wish to limit myself to thus mounting them or to there beingscrew-threads,since the same result might be accomplished by mechanical equivalents.

The mechanism for regulating the contact with the brush 9 may be described as follows:

118 an idler guide-roll.

119 is a guide mounted upon eccentric journals 120, so that by being oscillated on its journals the cloth may be made to approach or recede from the brush 9. Connected with one of these journals 120 is a slotted segment 121, provided with the handle 122, whereby the eccentric guide 119 may be oscillated. For the purpose of locking the segment at the desired point a set-screw 123 is provided, which extends through said slot, but is provided with a shoulder 124, adapted to enter any of the enlargements 125 of the slot and lock the segment.

While I have herein shown and described my invention as applied to a machine having a brush-cylinder covered with bristles, the covering material of the cylinder forms no part of my present invention, and, in fact, may be of any material used in treating clothsas card, sandpaper, &c. My invention relates not to the cylinder-covering, but to the cloth-guiding mechanism and the means for shifting the same, as will appear from an inspection of the claims. I do not therefore wish to be understood as limiting myself to the use of my invention with a bristle-covered brushing-cylinder only, but to claim it as applied to cloth-treating machines having cylinders covered with any material.

I claim- 1. In a cloth-treating machine, in combination, the frame, the brush, the bearings for the brush on said frame, a pair of top guides, a pair of bottom guides and common operating means whereby all four of the guides are moved laterally to and from said brush in unison, substantially as described.

2. In a cloth-treating machine, in combination, the frame, the brush, brush-bearings on said frame, guides 43 and 46 below the level of said bearings, guides 44 and 45 above the level of said bearings, levers supporting said guides 44 and 45 and extending downward to points substantially outside of said guides 43 and 46 and common operating means for said levers and guides, substantially as described. 1

3. In a cloth-treating machine, in combinati0n,the frame, the brush, a shaft 37 extending 1 below the level of the brush-journals, arms journaled to the frame and extending upwardly on opposite sides of said brush above the same, guides 44 and 45 on said arms above said brush and on opposite sides of the vertical plane through the axis of said brush and mechanism connecting said arms with said shaft, respectively, on opposite sides of said vertical plane whereby the mechanism controlling the guides which hold the cloth extended above the level of said brush is located on opposite sides and below said brush and in such position as not to obstruct the upward removal of said brush, substantially as described.

4. I11 a cloth-treating machine, in combination, the frame, the brush, the bearings for the brush mounted on top of the frame, guides 43 and 46 below the level of said bearings, guides 44 and 45 above the level of said bearings, levers supporting said guides 44 and 45 and extending downward to said frame and common operating mechanism whereby all of said guides are moved laterally in unison, substantially as described.

5. In a cloth-treating machine, in combination, the frame, the brush, the brush-bearings on said frame, the guides 43, 44, 45 and 46, carriages 51 and 52 for the bearings of said guides 48 and 46, levers carrying the bearings of the guides 44 and 45 and means connecting said carriages and levers whereby those on opposite sides of the brush are moved inversely, substantially as described.

6. In a cloth-treating machine, in combination, the frame, bearings on top of the frame, a brush journaled in said bearings on top of the frame, a steamer 11 and folder 1 5 mounted on said frame, respectively beforeand behind said brush, a scray or cloth-receiver beneath said brush, guides 43 and 46 below the center of said brush and respectively before and behind the same, means whereby the cloth is led from said guide 46 to said folder, said cloth-receiver, said steamer and said guide 43 successively, guides 44 and 45 located substantially at a plane tangent to the top of said brush and supports from below for said guides 44 and 45 respectively before and behind said brush, substantially as described; whereby all of said parts are so arranged as not to obstruct the upward removal of said brush.
